So on anything but low heat I start the dryer and it runs for about a minute then completely shuts off. It will re-start but does the same thing. On low heat, it will run the full timer cycle. I replaced the heating element last year but not the thermostat or the thermistor. Could these be the problem?

Thanks in advance.

--->Unplug the dryer, measure the thermistor resistance using a multimeter. You should measure around 10,000 ohms of resistance at room temperature. Replace the thermistor if resistance is off. If thermistor resistance is okay and the wire harness is intact, replace the electronic control board.

Here's the thermistor for your model you can order:
DC32-00007A Dryer Thermistor

Let us know what you find.

Jake,
I finally got time to look at my dryer issue. With the dryer unplugged I tested both switches as I didn't know which is which. At either rate, with my multimeter set on what's shown I got zero on both of them. Am I testing this correctly? I also ran the dryer and the heating element gets red for about a minute then shuts off and then a minute later the machine stops running.

Set the multimeter at the lowest ohms setting to ohm test those thermostats for continuity, for yours its 200. You have it on 20k in the photo.

Your thermistor should be located on the blower wheel housing, set your meter on 20k to ohm test that one.

When you click the thermistor part I posted above, you will see a video of where its at.:)

ok s found the thermistor and set the ohm meter on 200 and it measured 13.8. So I assume that's good?

Ok, that's close enough.

If you run the dryer on NOT HEAT/AIR FLUFF, does the dryer stay running?

So I don't have a no heat setting so I ran it on the lowest setting and it ran a full cycle.

Wrinkle Away should be NO HEAT.

Also if you have it on HIGH or MED heat and the dryer shuts off in about a minute can you restart it again immediately? If not, does the motor make a hum sound like it wants to start but can't?

Jake,

So I ran it on the low setting as shown above as I do not have a no heat option. On Low heat it ran a full 30 minute cycle. ( I started watching a movie on my phone while sitting in the laundry room) and it ran the full cycle. So I figured what the heck, I did a small load of laundry and threw it in the dryer and ran a normal cycle high heat 35 minutes and it worked perfect???? (finished the movie)

So I'm not sure what happened.

I really do appreciate your help and patience!

Chris

Ok Chris, it seems to be working now?

Also make sure the dryer motor isn't clogged up with lint build-up. That will make the motor overheat and shut down prematurely.

It seems to be Jake. There was a lot of lint I vacuumed out so maybe that was it.

Again, thanks for the help. Much appreciated.

Have a great Christmas!
